Hi guys, I have this problem with replacing the 2 " green light bulbs " behind the AC/Heater unit in my Corolla 2003.

I know how to get to the unit behind the clock but I can't get behind the plastic piece holding the control to even stick my hand in there to get to bulbs. I keep taking it apart trying to figure this one out but I don't know.

There is this thick wire attached to the back of it controlling the rotators. I am just running out of ideas. Any advice will be greatly appreciated. Is there a way to deattach that wire for easier access ?
